SEAliflI-GLEAT FOR SHEET- ROOFING.

Specification of Letters Patent.

Patented Apia. H5, 1918.,

Application filed December 12, 1916. Serial No. 136,433.

To all who-m it may concern:

Be it known .that l, ALBERT C. F scnnn, a citizen of the United. States, residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful lin 'irovements in Seam- Cleats for Sheet-Roofing, of which the following is a specification.

This invention relates to an iinprovei'nent in seam cleats for sheet roofing, and has for one of its objects to provide seam cleats in the form of nail spacing strips so that the cost of manufacture may be materially reduced, and that less labor, comparatively,

will be required in securing them to the roofs of buildings than the seam cleats heretot'ore generally used. A further object is to provide such a construction that each cleat will. be reinforced throughout its on tire length to prevent buckline'. The invention includes a metallic strip bent at uniform intervals 0' its length toprovide loops or sockets for nail supports, nails maintained in the loops and provided with a sealing or adhesive member, so that when the nails are completely driven, the adhesive members will till any unoccupied parts of the nail holes in the roof boards and rooting Shorts, to exclude moisture, the loops at their lower ends being,' of flaring shape for this purpose. \Vith the above objects in. view and others to be mentioned. hercinz'ifter the invention presents a novel construction, combination and arrangei'nent of parts as described and claimed, and as illustrated in the accompanying drawing, wherein,

Figure 1 is a view in side elevation of a part of; a seam cleat. Fig. 2 is a plan view of the same. liig. 3 is a reverse side View of the parts shown in Fig. 1. Fig. 4. is a view showing a, root board and rooting sheets in section, with a seam cleat applied Fig. 5 is a perspective view showing a part of a roof and parts of roofing sheets disposed in overlapped relation secured to the root', in part, by means of the seam cleats. Fin". (3 is a sectional view through one of the loops, said view being a. detail relating to Fig: 4;, on an enlarged scale. Fig 7 is a transverse section on line .7 7 of Fig. 5.

Referring now tothc drawing for a more longitudinalintervals with loops 9, each loop preferably being bell shaped or flaring at its lower end adjacent to the flange as indicated at Z). Nails or similar impaling members 10 are disposed in the loops, each having a head of, suilicient width that it may extend transversely, outwardly of the upper end of a loop, and having a length greatenthan the width of the strip; and that part of each nail which projects below the flange a and lowerjedge of the strip is provided with an appendage 11 of any suitable adhesive material impervious to moisture.

Numerals 12 indicate patches of adhesive material, each being secured upon the 0pposed parts of the metallic strips opposite to a loop, this being a desired feature generally, but may be omitted in somc'instances; and while the flange a. for each strip is a. desired feature and may be formed without appreciable expense, I do not Wish to be understood as limiting myself to its use. I

The device is of great advantage for securing the roofing sheets upon a roof as compared with rooting cleats her itofore used for that purpose, one of the reasons being that the nails are held in the loops ready to be driven into. the root boards 13, the time usually required by workmen in picking;' up the nails being saved; also Workmen olfleu cause nails to be scattered about when securing ordinary seam cleats to the roofing sheets of roots, which frequently cause the sheets to become torn, and results in a loss of the nails; and it will be seen that, by use of the herein described device, the nails will be disposed at uniform distances from each other.

It will be understood that the roofing sheets 14: and 15 are disposed with their edges or parts adjacent thereto in over lapped relation, the device being used to secure them to the rool boards 13, and in operation the strip 8 may be manually disposed and n'iaintained edg'cwise, the flange n. engaging the uppermost sheet and the nails bein disposed. at right angles to the roof boards; and by use of a hammer or similar tool the nails are driven into the boards, lhrough the sheets, until the flange a is firmly seated upon the uppermost roofing sheet.

The edges of the strip 8.,arc substantially parallel, and since the flange c is.rectilinear, the parts of each strip between the loops 3,530 @praiing to 11: iii; seaside-ram .01: the ism.
